Vaginal cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of vaginal cancer remains unknown. This cancer generally occurs in women in their early to mid-50s, but some of the rarer types occur in younger women, and rhabdomyosarcoma appears in children. (Clear cell adenocarcinoma has an increased incidence in young women whose mothers took diethylstilbestrol).
Vaginal cancer varies in severity according to its location and effect on lymphatic drainage. (The vagina is a thin-walled structure with a rich lymphatic drainage.) Vaginal cancer is similar to cervical cancer in that it may progress from an intraepithelial tumor to an invasive cancer. However, it spreads more slowly than cervical cancer.
A lesion in the upper third of the vagina (the most common site) usually metastasizes to the groin nodes; a lesion in the lower third (the second most common site) usually metastasizes to the hypogastric and iliac nodes; but a lesion in the middle third metastasizes erratically. A posterior lesion displaces and distends the vaginal posterior wall before spreading to deep layers. By contrast, an anterior lesion spreads more rapidly into other structures and deep layers because, unlike the posterior wall, the anterior vaginal wall isn't flexible.

Malignant spinal neoplasms:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Primary tumors of the spinal cord may be extramedullary (occurring outside the spinal cord) or intramedullary (occurring within the cord itself). Extramedullary tumors may be intradural (meningiomas and schwannomas), which account for 60% of all primary malignant spinal cord neoplasms, or extradural (metastatic tumors from breasts, lungs, prostate, leukemia, or lymphomas), which account for 25% of these malignant neoplasms.
Intramedullary tumors, or gliomas (astrocytomas or ependymomas), are comparatively rare, accounting for only about 10%. In children, they're low-grade astrocytomas.
Spinal cord tumors are rare compared with intracranial tumors (ratio of 1:4). They occur equally in men and women, with the exception of meningiomas, which occur mostly in women. Spinal cord tumors can occur anywhere along the length of the cord or its roots.

Vaginitis:
Vaginitis - epidemiology
(The 5-Minute Pediatric Consult)
- Candidiasis may present cyclically with menses, possibly owing to changing estrogen levels.
- Gonorrhea is more likely to be symptomatic at the time of menses owing to easier access to the upper reproductive tract.
- Body mass index (BMI) at the extremes is associated with increased risk of vulvovaginitis.
- The epidemiology of bacterial vaginosis is not well known because it is not a reportable disease, and 50% of cases may be asymptomatic.
Vaginitis - incidence
The exact incidence of vaginitis is unknown.

About prevalence and incidence statistics:
The term 'prevalence' of Vagina cancer usually refers to the estimated population
of people who are managing Vagina cancer at any given time.
The term 'incidence' of Vagina cancer refers to the annual diagnosis rate,
or the number of new cases of Vagina cancer diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
